Definitions
- This invention relates to a method for preparing graphitic carbon nitride materials having a carbon to nitrogen molar ratio of about 3:4 by pyrolysing non-metallic rodanides in a simple and economically feasible manner.
- Prepared carbon nitride materials have outstanding properties and can be used in applications such as wear and corrosion resistant coatings, electronics, optical coatings and in various composite materials.
- Carbon nitride materials have been the focus of considerable experimental and theoretical attention since Cohen and co-workers proposed that ⁇ -C3N 4 , a carbon nitride material analogous to ⁇ - Si 3 N 4 , should have hardness comparable to that of diamond. Subsequent calculations have shown that other crystalline C 3 N 4 should have stabilities comparable or greater to that of ⁇ -C 3 N 4 , and that many of these structures should be hard by nature.
- the C 3 N 4 -structures include ⁇ -, ⁇ -, cubic-, pseudocubic-, and graphitic carbon nitride. Additionally, C 2 N2, although possessing different chemical structure, is called carbon nitride.
- the local structure property that distinguishes potentially super hard and dense C 3 N 4 structures from low-density, softer material is carbon coordination: hard materials require tetrahedral or sp 3 -bonded carbon in the C 3 N 4 -network, while sp 2 -bonded carbon will lead to much softer materials.
- This requirement of having sp 3 -bonded carbon in a hard carbon nitride is completely analogous to that in amorphous diamondlike carbon (DLC), Hu et al, Physical Rewiev B, vol 57, 1997, number 6, pages 3185-3188, Nitrogen-driven sp3 to sp2 transformation in carbon nitride materials.
- DLC diamondlike carbon
- carbon nitride coatings possess excellent wear- and scratch-free properties. Additionally, carbon nitride materials are corrosion resistant and can act as electrical insulators, optical coatings, and above all, they possess remarkably better thermal resistance than obtained with corresponding DLC-coatings.
- the present industrially produced carbon nitride coatings/thin films are amorphous with nitrogen content less than 50%, i.e. not C 3 N 4 - structures.
- amorphous CN x -materials Due to their easier availability, the amorphous CN x -materials have already found a wide spread of applications. It is for instance the most widely used material in protective overcoats for hard disks, Widlow et al, Brazilian Journal of Physics, 2000, vol 30, n:o 3, Recent Progress in the synthesis and characterization of amorphous and crystalline carbon nitride coatings. Such films are generally produced by various film deposition methods by ablating graphite in pure nitrogen the resulting films comprising amorphous carbon nitride having wear performance several times better than existing coatings.
- the drawback is the fact that the method does not allow to prevent the formation of H 2 and HCN as by-products. This results in an elevated explosiveness and toxicity of the process; [Montigaud H., Tanguy B., Demazeau G., Alves I., Courjault S. C 3 N 4 : dream or reality? Solvothermal synthesis as macroscopic samples of C 3 N 4 graphitic form // J. of Materials Science. 2000. V.35. pages 2547-2552].
- UV photo-assisted synthesis has been employed to prepare a carbon nitride target by reacting an alkali-metal amide, such as sodium amide, as a nitrogen source with alkyl chloride, such as chloroform, as carbon source;
- alkali-metal amide such as sodium amide
- alkyl chloride such as chloroform
- the reaction involves steps of decomposing the unreacted starting materials by series of pumping and filtration processes, and a tedious process to remove alkali chloride by-product.
- the powder material is then sintered at 800 0 C to yield the target material containing C, N and H, the nitrogen to carbon ratio being still only 0.23.
- the present invention now resolves the problems mentioned above.
- the invention relates to a method for preparing carbon nitride materials by pyrolysing non-metallic rodanides to give carbon nitride materials having a carbon to nitrogen ratio of about 3:4 in a simple and economically feasible manner.
- the method produces graphitic carbon nitride materials that can in turn be employed for preparing carbon nitride material in different chemical and structural forms including but not limited to ⁇ -, ⁇ -, cubic-, pseudocubic-, graphitic- and amorphous forms of C 3 N 4 .
- the carbon nitride materials have outstanding properties and can be used in applications such as wear and corrosion resistant coatings, electronics, optical coatings and in various composite materials to improve the properties of for example metal-, glass- and polymer-derived products.
- the carbon nitride materials can be used as additives, for example as composites in metals, metal alloys, different kinds of polymer products as well as glass products. They can be used in manufacturing of electronics and semiconductors, manufacturing of household machinery and medical equipment, drilling, grinding and polishing products, in production of blue luminophore, in spray coating of computer hard disc, manufacturing of heavy duty tools used in metal processing, as solar cell materials etc.
- graphitic carbon nitride can be employed as fuel cell material and as a lubricant for difficult conditions.
- carbon nitride Since carbon nitride is both thermally and chemically very stable material, it will, if available in quantitative volumes, be utilized in many new applications such as coating chemical process apparatus, creep-strengthening, and improving wear and/or hardness properties of different metal grades for different purposes etc.
- One representative problem is for example creeping of copper materials when preserving nuclear waste for multimillenium time-frames.
- non-metallic rodanides such as ammonium rodanide can be employed efficiently and in economically efficient way in preparation of carbon nitride by simply pyrolysing said rodanides. Even when compared to pyrolysing alkali metal rodanides, the yields are increased and the production costs are decreased further. Since no alkali metal or metal traces are formed in the reaction, the product can now be obtained without tedious washing sequences to remove said side-products. If present, such side-products would have a seriously negative effect in the product applications.
- the production cost can be lowered by factor of 10-20 via using relatively cheap raw material and raising the yield of the ready-made end product.
- an actual manufacturing method for quantitative production of carbon nitride materials in particle form is provided.
- the pyrolysis is advantageously carried out in a reactor chamber which is built of at least two connected and sealed vessels in shape.
- a reactor chamber which is built of at least two connected and sealed vessels in shape.
- Such features allows for making the reaction process in a closed volume, which makes the whole process ecologically-friendly, ensures the high purity and the quick removal of any by-products and reduction of the C 3 N 4 production costs.
- the process is easily up-scaleable and due to relative harmless chemicals, several different reactor materials can be employed in manufacturing apparatus. This in turn reduces the overall manufacturing cost further.
- Figure 1a represents one possible embodiment of reactor vessel arrangement for preparing carbon nitride material.
- Figure 1b represents one possible embodiment of reactor vessel arrangement for preparing carbon nitride material.
- the present invention is directed to a method for preparing carbon nitride material, wherein organic rodanide is pyrolysed to give carbon nitride material.
- pyrolysis is here meant decomposition or transformation of a compound caused by heat.
- rodanides is here meant thiocyanate/iso- thiocyanate (SCN; CNS) compounds.
- SCN thiocyanate/iso- thiocyanate
- carbon nitride materials is herby meant different CN x , C 2 N 2 and, especially C 3 N 4 materials.
- organic is hereby meant all non-metallic compounds, also those not containing carbon in the molecular skeleton.
- metals is hereby meant all kinds of metals, including alkali metals.
- the method according to the invention enables use of all kind of non- metallic rodanides in preparation of carbon nitride materials.
- An especially preferred non-metallic rodanide is ammonium rodanide, NH 4 SCN.
- the rodanides can be employed alone or as mixtures.
- the reaction can be catalyzed with appropriate catalysts.
- a non-limiting example is zinc-derived catalysts, such as zinc chloride.
- the pyrolysis is preferably carried out in the substantial absence of oxygen and/or hydrogen. Most preferably, the pyrolysis is carried out in complete absence of oxygen and/or hydrogen. The presence of oxygen dramatically lowers the yield of the product, and hydrogen increases the risk of explosions.
- such conditions can be achieved by carrying out the pyrolysis in vacuumized conditions.
- the pressure can between 10 "1 - 10 "9 mmHg, preferably 10 "3 - 10 "7 mmHg and most preferably between 10 "4 - 10 ⁇ 6 mmHg, possibly using inert gas flow to remove gaseous impurities.
- the pyrolysis of organic rodanide or rodanides is carried out under a high purity inert gas atmosphere.
- inert atmospheres comprise nitrogen, helium or argon.
- the pyrolysis is carried out with a gradient of T max ⁇ 85O 0 C, T min ⁇ ambient temperature.
- the pyrolysis is carried out with a gradient of T max ⁇ 650 0 C, T m j ⁇ ⁇ ambient temperature.
- the pyrolysis is carried out with a gradient of T max ⁇ 500 0 C, T min ⁇ ambient temperature.
- rising the temperature over 500 0 C is not justifiable, as it may lead to partial decomposing of CsN 4 , thus lowering the yield of the product.
- Different starting materials act differently, and different temperatures can typically yield different structures of carbon nitride materials.
- the polymer size and thus the exact hydrogen content and C:N -ratio of the product compound can be tuned by employing different temperatures. Therefore, the scope of the invention is not restricted to said temperature gradient.
- the temperature gradient is created essentially throughout the chamber.
- chamber is here meant a reactor, in which the pyrolysis is carried out.
- the formed CS 2 and volatile impurities are essentially condensed in such part of the reactor, which is essentially free of carbon nitride material.
- Formed organic sulphide compounds such as ammonium sulphide (when employing ammonium rodanide) can preferably be washed off the end product CaN 4 with water.
- the reactor is not restricted in shape or material and can be of different metal grades, glass, ceramics etc. Two possible laboratory scale quartz tube reactors are described in figures 1 a and 1 b.
- the invention accomplishes preparation of carbon nitride material comprising graphitic structure in desired molecular ratios.
- carbon nitride material has an atomic ratio of carbon to nitrogen of about 3:4.
- Carbon nitride material is produced in particle form, but can be worked into powders, flakes, films, fibers, foams, foils, micro foils, granules, insulated wires, honey comb, dispersions, laminates, lumps, mesh, metallised films, non-woven fabrics, monofilament, rods, sheets, single crystals, spheres, tubes, wires and for example sputtering/pulsed plasma arc-discharge/laser ablation targets.
- Normal powder processing methods such as mixing, tabletting and sintering techniques can be utilized in production.
- ammonium rodanide in quantity of 10.00 g was taken, loaded into a reaction chamber, which was made of quartz glass and shaped as two connected vessels.
- the chamber was vacuumized to pressure of 10 "4 - 10 "5 mmHg and sealed.
- the following reaction was conducted for 12 hours:
- ammonium rodanide in quantity of 10.00 g was taken, loaded into a reaction chamber, which was made of quartz glass and shaped as two connected vessels.
- the chamber was vacuumized to pressure of 10 '3 - 10 '4 mmHg and sealed.
